Re: [Electric Boats] MARS BLDCmotor

John,

The 20 turn and the 28 turn motors produce the same power. I got a new motor pulley & belt for the 28 turn so both motors turned the prop shaft the same speed.

I returned the new pulley & belt to the bearing house and am selling the new motor.

Why are you selling this as opposed to the 20 turn if it runs with less
speed? It seems like it is better than your 20 turn unit. John
